[U-Boot-Users] Acknowledging the use of U-boot in an embedded project
by Steven Bass 21 Jul '08

21 Jul '08

I've just become involved in a project which is using U-boot as the bootloader. This is a smallish embedded system. I'm trying to find the right way to handle the use of U-boot. What sort of acknowledgements, source code availability, etc. are expected here. U-boot isn't ever visible to the user; the system boots up and launches the application. There is a small LCD screen; and really nowhere to display much. Minor changes have been made to the U-boot source; to customize it for the hardware and the software download of new firmware. Thanks, Steve Steven Bass Intertech Engineering Associates, Inc. (781) 801-1130

[U-Boot-Users] [PATCH] mpc85xx: make the MxMR register in upmconfig as a parameter
by Sebastian Siewior 21 Jul '08

21 Jul '08

The default value for the MxMR register is not always the right one. This patch adds the value of MxMR register as an additional parameter (plus a few defines instead of hex coded values).
